So I've been SLOWLY working on my 93 rx7 and I took it for a short test drive the other day and the car wouldn't boost at all and the check engine light came on. So I put the car into diagnostic mode and I get code 27 which is supposedly the for the oil metering pump. The fsm doesn't show code 27 in it cause I looked there first then searched the net and found the code on banzai racings site. So my question is what usually causes this code to be thrown? I am guessing a leaking omp? Just guessing cause my car leaks a bit of oil although I was guessing before this happend it was the oil pan.

RX7 FD & Series 5 Error Codes

 

The code is not generated due to a leak. The FSM sets out some checks to be made, but AFAIK, it usually just means the OMP needs changing. ----> https://www.rx7club.com/3rd-generati...my-how-675341/

 

I have a good condition OMP if you need one. PM me
